Detroit DD16 EPA10 (2010-13) Fault Code: SPN 5016 FMI 3 (ACM) Coolant Valve Supply Voltage Failed High

DESCRIPTION:
High side digital output circuit shorted to power.

MONITORED PARAMETER:
High sided digital output.

TYPICAL ENABLING CONDITIONS:
Always on

MONITOR SEQUENCE:
None

EXECUTION FREQUENCY:
Continuous when enabling conditions met.

TYPICAL DURATION:
2 Seconds

DASH LAMPS:
1. MIL
2.CEL

ENGINE REACTION:
None

VERIFICATION:
Key Cycle

NOTE: The supply voltage circuit is networked internal of the Aftertreatment Control Module (ACM). This circuit supplies voltage to the Coolant Valve, Purge-in-process indicator (if equipped), and the Inlet NOx sensor. A short to power on any one of those circuits will set this fault code.

PROBABLE CAUSES:
1. Coolant valve connector/harness.
2. Failed ACM (Aftertreatment Control Module).
